Each water tank is provided with air inlet and outlet valves on both sides. When the water tank needs to increase oxygen, the corresponding air inlet and outlet valves of the water tank are opened, and the air inlet and outlet valves of other water tanks are closed. Then the air inlet and outlet valves are opened in turn to inject sufficient oxygen into the water tank. The excess oxygen is returned to the main airway through the air return valve, so that it can enter the next water tank connected by the branch airway. In this way, the sealing cover is used to increase the pressure in the tank, so that oxygen is more easily dissolved in fresh water products, making it easier for the water products in the tank to absorb oxygen. Due to the increase in air pressure in the tank, oxygen flows into the next tank through the air return airway in the tank, providing oxygen for the fresh water products in the tank. This forms a series of oxygenation, achieving the purpose of saving oxygen. When a water tank does not need to supply oxygen, the corresponding air inlet and outlet valves of the water tank are closed, and the corresponding control valve is opened. This series structure does not need to deliver oxygen to each water tank separately, but only needs to continuously release oxygen to the first water tank. The pressure difference between the first and last water tanks is used to transfer oxygen to each water tank in turn, thereby achieving the purpose of saving oxygen. BRIEF DESCRIPTION OF DRAWINGS

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] Example 1

[0020] like Figure 1 As shown, a series oxygen supply structure for aquatic product tanks includes an aquatic product tank 1 with a sealing port 2 that matches it. A main air channel is provided on the liquid oxygen 3. A main valve 4 is provided at the end of the main air channel, and a monitor 11 for monitoring the oxygen flow rate of the main air channel is provided at the end. Several branch air channels are connected to the main air channel, and each branch air channel is connected to the aquatic product tank 1. An aquatic product tank inlet / outlet valve 6 is provided on the branch air channel below the main air channel. The end aquatic product tank 1 and the tail aquatic product tank 1 are connected by an oxygen supply pipe. The pressure value of the end aquatic product tank 1 is greater than the pressure value of the tail aquatic product tank 1.

[0021] The aquatic product tank air inlet / outlet valve 6 includes control valves A61, B62, C63, D64, and E65, which respectively control the opening and closing of branch air passages.

[0022] Both ends of the aquatic product tank 1 are provided with quick connectors 5 for connecting branch air passages, and the quick connectors 5 are arranged in a stepped manner.

[0023] The branch air passage is provided with an air inlet valve 7 to form an air inlet passage on one side of the aquatic product tank 1, and the air passage on the other side is provided with a return air valve 8 to form a return air passage. The return air passage is connected to the air inlet passage of the next aquatic product tank 1.

[0024] The air intake valve 7 includes air intake valve A71, air intake valve B72, air intake valve C73 and air intake valve D74, which control the oxygen supply to each aquatic tank 1.

[0025] The return air valve 8 includes return air valves A81, B82, C83 and D84 that control the recovery of oxygen in each aquatic tank 1. The aquatic tank 1 at the end has only an air inlet valve D74 on one side and an air outlet 9 on the other side. The air outlet 9 is used for pressure relief and is normally open.

[0026] The return air duct of the first aquatic tank 1 is connected to the return air duct of the last aquatic tank 1 through an oxygen supply pipe. The oxygen supply pipe is equipped with a control valve 10. The control valve 10 includes an oxygenation control valve A101, an oxygenation control valve B102, an oxygenation control valve C103, and an oxygenation control valve D104, which control the closure of the oxygen supply pipe in the area where each aquatic tank 1 is located.

[0027] Operating Procedure: Liquid oxygen 3 is activated, main valve 4 is opened, control valve A61 on the main air duct is opened, control valves B62 to D64 are closed, and return air valves A81 to D84 are closed. Simultaneously, oxygenation control valves A101 to D104 on the oxygen supply pipe are closed. Air inlet valve A71 on aquaculture tank 1 is opened, and return air valve A81 is closed. Oxygen is supplied to the first aquaculture tank 1 through the branch air duct. When oxygen overflows from the water in aquaculture tank 1, due to the sealing effect of sealing port 2, the pressure value of the end aquaculture tank 1 is greater than that of the tail aquaculture tank 1. Return air valve A81 is then opened. Since oxygenation control valves A101 to D104 on the oxygen supply pipe are all closed, excess oxygen can only flow through the return air duct and oxygen supply pipe into the air inlet circuit of the next aquaculture tank 1. In the middle, oxygen is refilled into the second aquatic tank 1, and so on until the end aquatic tank 1, realizing series oxygenation and achieving the purpose of saving oxygen. Then, excessive pressure and carbon dioxide are discharged through the air outlet 9 on its side. The monitor 11 at the end of the main air channel monitors the oxygen flow in the main air channel. If the oxygen flow is too low, it means that the air passage of the air inlet / outlet valve 6 of a certain aquatic tank is not smooth, and it can be repaired. If a certain aquatic tank 1 does not need to be oxygenated, it is only necessary to close the corresponding air inlet valve 7 and return valve 8. This series structure does not require oxygen to be supplied to each aquatic tank 1 separately. Only liquid oxygen needs to be injected into the first aquatic tank 1. Using the pressure difference between the first and last aquatic tank 1, oxygen is transferred to each aquatic tank 1 in sequence, thereby achieving the purpose of saving oxygen. The number of aquatic tanks 1 in series is determined according to actual needs.

[0028] Example 2

[0029] like Figure 2 As shown, a series oxygen supply structure for aquatic product tanks includes an aquatic product tank 1, which has a sealing port 2 that matches it. Liquid oxygen 3 is connected to the aquatic product tank 1 through an air passage. A main valve 4 is provided at the end of the air passage. Several aquatic product tanks 1 are connected in series through branch air passages.

[0030] The aquatic product tank 1 has quick-connect fittings 5 ​​for connecting air passages on both sides in a stepped manner.

[0031] The terminal water tank 1 has only one quick connector 5, and the other side is provided with a gas outlet 9 for pressure discharge, and the gas outlet 9 is in a normally open state.

[0032] The working process is as follows: the liquid oxygen 3 is opened, the total valve 4 is opened, the oxygen enters the first water tank 1 through the gas channel, and then enters the subsequent water tank 1 through the branch gas channel in series, when the pressure in the water tank 1 is too large, the pressure and carbon dioxide are discharged through the gas outlet 9 of the terminal water tank 1, this series structure does not need to release a large amount of oxygen, only the oxygen that can be contained in each water tank 1 is needed, and the number of the series connection of the water tank 1 is determined according to the actual needs.
